Massen-, NMR-und IR-spektroskopische Untersuchungen an Berylliumchelaten substituierter Acetoacetanilide / Investigations of Beryllium Chelates with Substituted Acetoacetanilides by Mass, NMR and IR Spectroscopy

Abstract

Correlation of measurements by mass, NMR and IR spectrometry were carried out for the determination of the structure and stability of beryllium chelates of substituted aceto-acetanilides. The substituents at the phenyl ring of the amide group influence the position of the stretching vibrations of the beryllium-oxygen bonds, the chemical shift of the amide proton and also the abundance ratios of specific ions of fragments in the respective mass spectra. All these results are correlated and represent data for the stability of these metal chelates
